Errors related to creating and managing components.

Variants

NoPrimaryInstance

Primary instance of a given component is not specified, if many components exist for a given type, or not component registered at all.

Fields

type_id: TypeId

type_name: Option<String>

IncompatibleComponent

Tired to case one type to another, incompatible one.

Fields

type_id: TypeId

type_name: String

NoNamedInstance(String)

Cannot find component with given name.

UnrecognizedScope(String)

Component registered for unknown scope - possibly missing associated ScopeFactory.

DependencyCycle

Found a cycle when creating given type.

Fields

type_id: TypeId

type_name: Option<String>

ConstructorError(ErrorPtr)

Custom constructor returned an error.

Trait Implementations

impl Clone for ComponentInstanceProviderError

fn clone(&self) -> ComponentInstanceProviderError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ComponentInstanceProviderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ComponentInstanceProviderError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ComponentInstanceProviderError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
